Question 1

Service-oriented architecture must be designed to be both integration-centric and silo-based.

Accepted Answer

A) True 
 B)False  False

Question 2

Which of the following is not a benefit of maintaining a vendor-neutral and business-driven context for a service-oriented architecture?

Accepted Answer

A)   Establish a technology architecture with a fixed scope and purpose that remains unchanged, regardless of how the business may need to change over time.
B)   Avoid establishing a technology architecture that will need to be replaced in the near future when it no longer adequately fulfills business requirements.

Question 3

Which of the following statements are false?    SELECT ALL THAT APPLY

Accepted Answer

A)   Service compositions are aggregates of non-service-oriented applications that are grouped together and exposed as a service.
B)   Service compositions are aggregates of services that are grouped together to carry out a specific task.
C)   Service compositions can be classified as service-oriented solutions.
D)   Service composition design is not a common consideration with SOA projects. The emphasis of service-orientation is on producing services that are solely optimized for point-to-point data exchange. A,D

Question 4

Which of the following is an expected result of successfully adopting SOA?

Accepted Answer

A)   A natural increase in runtime performance that you will gain as a result of the fact that service compositions will often be comprised of a greater amount of individually participating programs (services)  than traditional distributed applications.
B)   The fact that the existing IT organizational structure will not have to change because of how well a service-oriented enterprise fits into traditional IT departmental structures that are focused on project-centric application delivery.
C)   The tactical (short-term)  focus of service-orientation, which allows for the initial rapid delivery of services without concerns about their subsequent governance.
D)   The strategic (long-term)  target state that is attainable when many of the services delivered are interoperable and reusable, thereby allowing for them to be repeatedly composed in response to new and changing business requirements.

Question 5

Service-oriented computing advocates establishing a technology architecture with increased vendor technology diversity, which means that service-oriented solutions need to be consistently built using different vendor technologies and products. This way, the failure of any one vendor technology or product will not bring down all services within a service inventory.  Select the correct answer.

Accepted Answer

A) True 
 B)False

Question 6

Which of the following statements are true?    SELECT ALL THAT APPLY

Accepted Answer

A)   A service inventory establishes a boundary for a collection of services.
B)   Service inventories represent collections of related services that are independently standardized and governed.
C)   The quantity of services within a service inventory will increase as new services that belong within the service inventory boundary are delivered.
D)   Service inventories are ideally planned and modeled ahead of time via the creation of service inventory blueprints.

Question 7

Two common, yet opposing SOA delivery approaches are:

Accepted Answer

A)   bottom-up and upside-down
B)   top-down and left-to-right
C)   upside-down and left-to-right
D)   none of the above

Question 8

A common security consideration with service-oriented solutions is the need to apply security at the transport layer as opposed to the message layer.  Select the correct answer.

Accepted Answer

A) True 
 B)False

Question 9

A common performance consideration when designing agnostic services is the fact that they contain generic processing logic which can decrease performance overhead, thereby reducing performance requirements.  Select the correct answer.

Accepted Answer

A) True 
 B)False

Question 10

You can create __________ or __________ service inventories.

Accepted Answer

A)   process-specific, process-wide
B)   domain, enterprise
C)   domain, process-specific
D)   enterprise, process-specific

Question 11

One of the fundamental characteristics of service-oriented architecture is:

Accepted Answer

A)   business-driven
B)   integration-centric
C)   inventory-neutral
D)   silo-driven

Question 12

"A primary focus of service modeling is the encapsulation and abstraction of business logic in support of defining business service candidates." What is wrong with this statement?

Accepted Answer

A)   Service modeling is a phase dedicated to defining non-business service logic only.
B)   There is no such thing as a business service when creating service-oriented solutions.
C)   The service modeling process results in the implementation of services, not the definition of service candidates.
D)   There is nothing wrong with this statement.

Question 13

Agnostic solution logic is logic that is considered single-purpose because it is unique to one task.  Select the correct answer.

Accepted Answer

A) True 
 B)False

Question 14

When designing service-oriented architectures, it is important to take the strategic goal of Increased Vendor Diversity Options into account, because this goal:

Accepted Answer

A)   encourages you to commit to one vendor platform and stick with that platform, which fosters long-term flexibility
B)   encourages you to retain the constant option of using proprietary vendor features and extensions so that they can be entrenched into your service-oriented architectures for long-term flexibility
C)   encourages you to retain the constant option to extend or replace parts of your service-oriented architectures with different vendor technologies or products, which fosters long-term flexibility
D)   encourages you to bridge disparity between vendor platforms by using modern transformation technologies for long-term flexibility

Question 15

Service metadata can be centrally registered within a __________ for discoverability purposes.

Accepted Answer

A)   service inventory
B)   service composition
C)   service registry
D)   service model

Question 16

Which of the following statements are true?    SELECT ALL THAT APPLY

Accepted Answer

A)   "Service-oriented computing" is an umbrella term that encompasses SOA and service-orientation.
B)   Service-oriented computing can be considered a distinct form of distributed computing.
C)   Because of its emphasis on agnostic services, service-oriented computing can be viewed as a departure from the traditional silo-based approach to application design.
D)   There are several goals associated with service-oriented computing, one of which is Reduced IT Burden.

Question 17

Accepted Answer

A)   consistently decreasing
B)   middleware-centric
C)   vendor-driven

B)   development-centric, quality assurance-centric
C)   enterprise-centric, project-centric
D)   development-centric, communication-centric

Question 19

When following the distinct lifecycle phases of an SOA delivery project you are:

Accepted Answer

A)   discouraged from involving business analysts as part of the definition of services so that services remain technically focused
B)   discouraged from involving technology experts as part of the definition of services so that services remain business focused
C)   encouraged to have business analysts and technology experts collaborate in the definition of services so that services have and retain an alignment of technology and business
D)   none of the above

Question 20

Service A invokes ServiceB. Service B invokes ServiceC. Service C invokes both Service D and Service E. In this runtime scenario, which services are acting as service consumers?

Accepted Answer

A)   Service A, Service B, Service C
B)   Service D, Service E
C)   Service A
D)   None, because a service cannot also be a service consumer.
